IPC: C22C1/04
Filed: 1957-05-16
Abstract: A high density, high strength, sintered metal composition or alloy is composed of W, Ni, Cu, and Mo, (apart from impurities) has a sintered density at least 93 per cent of a theoretical density of not less than 13.5 gm/ccm., is made by pressing and sintering particles of the constituent metals all of average size from 2 to 8m , and comprises W at least 65 per cent by weight, Ni and Cu in a ratio between 0.5 and 2.5 by weight and in such amounts that their sum is equal to 4 to 25 per cent of the weight of tin alloy, and Mo in amount from 0.1 to 1.5 times the combined weight of Ni and Cu.  There may also be present Fe in amount up to 1.5 times the sum of the Ni and Cu, but not exceeding 10 per cent of the alloy.  Preferably reducible compounds, particularly the oxides of the metals are used as starting materials and heater to produced prealloyed powder of 2 to 8m  which is then compacted and sintered.  Thus the oxides in amounts which will lead to the desired composition are mixed thoroughly and reduced by heating in hydrogen or cracked ammonia at 900 DEG  to 1100 DEG C., the resulting range of particle size depending upon the time, temperature, and bed thickness.  The resulting powder with or without glyptal as binder is compacted at 10-30 tons p.s.i. and the compacts sintered in a reducing atmosphere at between 1350 DEG  and 1500 DEG C., and preferably between 1400 DEG  and 1440 DEG C., for 4 to 60 minutes.

Abstract: 891,343. Carbonising coal. NEHEZVEGYIPARI KUTATO INTEZET. May 7, 1959, No. 15736/59. Class 55 (1). In a process for the carbonisation of non- bituminous coal, the non-bituminous coal is predried, passed into a pre-coking chamber and thence into an indirectly heated coking chamber provided with refractory walls; the coke emerging from the latter is cooled by a quenching gas itself obtained by cooling and de-tarring volatile distillation products of the process, the arrangement being such that the quenching gas after cooling the coke is passed up a vertical channel centrally disposed in the coking chamber and provided with apertures, through which the volatile distillation products may enter the channel, intermingle with the quenching gas and assist in heating the incoming non- bituminous coal. As shown, apparatus suitable for use in effecting the above process comprises a pre-drying chamber (not shown), a precoking chamber 2, an indirectly heated coking chamber 3 heated by flues 5 separated from the coking chamber by refractory walls and a cokecooling chamber 10 provided with a vertical, centrally disposed channel 7 passing from the coke-cooling chamber 10 to the pre-coking chamber 2, the channel 7 being provided throughout its length with apertures serving in operation to permit volatile distillation products to enter the channel. Lignite is specified as a non-bituminous coal. If desired the quenching gas may be admitted at a pressure greater than atmospheric and the rate of extraction of quenching gas and volatile distillation products from the pre-coking chamber is so adjusted that the pressure in the coking chamber is substantially the same as in the flues. An example is given.

Patent GB-612559-A (GB)
Title: Production of amino-acids for use in the production of polymeric materials
Filed: 1946-05-27
Abstract: Alpha-alpha disubstituted beta-amino-propionic acids are produced by hydrogenating a beta-nitro-propionic acid having two hydrocarbon substituent radicals directly attached to the alpha-carbon atom, these radicals may be lower alkyl, e.g. methyl or ethyl, two aromatic radicals containing only one aromatic nucleus, e.g. phenyl, tolyl or xylyl, or one lower alkyl and one mono nuclear aromatic radical.  The beta-carbon atom of the acids may additionally carry a hydrocarbon substituent radical, e.g. a lower alkyl or a mononuclear aryl radical as above.  Specified starting materials are nitro-pivalic acid, beta-nitro-alpha-alpha-dimethyl butyric acid, beta-nitro-alpha-phenyl-iso-butyric acid and beta-nitro-alpha-alpha-diphenyl-propionic acid (beta-nitro-alpha-phenyl-hydrotropic acid).  Hydrogenation is best conducted at temperatures from room temperature to 100 DEG  C. in the presence of a Raney nickel catalyst, e.g. while suspended or dissolved in an aqueous medium, the acid being preferably employed in the form of a metal salt, e.g. an alkali metal or alkaline earth metal salt or as an ester, e.g. its methyl or ethyl ester. The amino acid may be regenerated from the salt or ester produced by treatment with a mineral acid.  In an example, nitro-pivalic acid and barium hydroxide octahydrate are dissolved in water and then subjected to a hydrogen pressure in the presence of Raney nickel.  The catalyst is removed by filtration and the barium precipitated with sulphuric acid and then filtered off, leaving amino-pivalic acid in solution. Beta-nitro-alpha-phenyl hydrotropic acid may be similarly hydrogenated to the amino acid.  The beta-nitro-alpha-disubstituted acids may be prepared by adding hydrocyanic acid under alkaline conditions to the corresponding nitro-olefine followed by hydrolysis of the nitro-nitrile obtained, thus an alcoholic solution of nitro-isobutene may be treated with an aqueous solution of potassium cyanide, acetic acid added to release the nitro-nitrile which is then hydrolysed with aqueous caustic soda to nitro-pivalic acid. Specification 601,123, [Group IV (a)], is referred to.

Abstract: 357,609. Time-pieces. VALLI, A., 553, Defensa Street, Buenos Aires, Argentine. May 26, 1930, No. 16232. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 28, 1930.] [Class 139.] Dials.-In a twenty-four hour clock or watch, wherein the hour, numbers 1-11 and 13-23 are in pairs on rotary spindles for alteration of the series every twelve hours, an indicator bearing the numerals 0, 12, 24 is also used. The pairs 1, 13-2, 14-&c. are on spindles, of which one has a wheel 4 entrained with ten wheels 5, wheel 4 having a pawl 25 which coacts with a ratchet disc 9 which is free on the spindle and rigid with a wheel 10 meshing with a sector 14 on an arm 12 pivoted at 11 and having a pin 13 controlled by a cam 1 on the stem 2 of the hour hand, so that every twelve hours sector 14 rotates wheel 10 to change the number series. Pin 26 and arm 27 prevent backward rotation of wheel 4. At the top of the dial the numerals 0, 12, 24 are rigid with a triangular plate 6 having a stop 22 which, with arm 23, prevents backward movement and a spring 24 aligns the plate on each of its three angular positions. A pawl 21 on plate 6 coacts with a disc 7 with two teeth, this being freely mounted and rigid with a wheel 8 which meshes with a sector on an arm 16 which is pivoted at 15 and has a roller 17 coacting with arm 12 and cam 1. Fig. 1 shows the position just before midnight, the numerals 13 .. 24 being visible beyond the edge of the masking disc 28. Shortly after midnight cam 1 reaches the position of Fig. 2, the arm 12 moving to change the number series and arm 16 moving to rotate disc 7 and plate 6 through 120‹ changing the hour number " 24 " to " 0." At 1 a.m. roller 17 drops off the point of cam 1, disc 7 rotates plate 6 a further 120‹ and hour numeral " 0 " changes to " 12." Just before noon cam 1 restores arm 16 clockwise so that disc 7 is rotated backwards 240‹, plate 6 remaining stationary, at the same time lever 12 also rotates disc 9 counterclockwise but parts 26, 27 hold the wheels 4, 5 stationary. Shortly after noon disc 7 rotates forward 120‹, but this merely brings a tooth on disc 7 up to pawl 21. At 1 p.m. the next rotation of disc 7 through 120‹ changes the number shown by plate 6 from 12 to 24. At the same time lever 12, rotating counterclockwise, rotates wheels 4, 5 clockwise to change the hour numbers from 1 .. 11 to 13 .. 23.
